IMPROVEMENT IN HVDROCARBON-YAPOR BURNERS.

Specification forming part of Letters Patent No. 191,170, dated May 22,1877; application filed September 6, 1876,

To all whom it may concern: I

Be it known that I, ROBERT W. PARK, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Hydrocarbon-Vapor Burners; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification, in which- Figure 1 is asectional view of my invention.

The nature of my invention consists in the peculiar construction,combination, and arrangement of parts, as hereinafter more fully setforth, having reference particularly to the following points: first, toextending the retort down into the reservoir, so that the heat of theformer may be conducted directly to the latter, and cause thevaporization of the liquid contents therein second, to the provision ofapertures in the retort extension, whereby the vaporized oil or gas maypass from the upper part of the reservoir into said retort; third, tothe employment of a regulatin g-screw passing through the body of thereservoir, and operating to adjust the flow of gas from the retort tothe burner.

Referring to the accompanying drawing, A designates the shell or outercasing of the lamp, surrounding a reservoir, B, in such manner as toleave an air-chamber, 0, having inlet and outlet openings 0 0',respectively. D represents a retort located above the reservoir B,having an extension, D, which passes down into' the said reservoir. Saidretort-extension is furnished or formed with apertures d (I, locatednear the top of the reservoir, to permit the vaporized oil or gas in theupper part of the latter to pass readily into the retort. Other openingsd d are formed in said extension at a lower point, and its lower edge isscalloped or cut away at d for a like purpose, viz., the passage of thevaporized oil from the reservoir to the retort. E represents a screw orthreaded spindle, which passes through a threaded opening in the bottomB of the reservoir B. The lower end of said screw is provided with athumb-piece, 6,

while its upper extremity tapers to a fine point, e, which centers in apin-hole, d, in the screw-neck D of the retort. F represents the burnerscrewed on the neck D, and G a sleeve terminating in a cup, g, saidsleeve fitting on the retort D, and the cup surrounding the stem of theburner.

The operation is substantially as follows:

The reservoir and retort are both packed with wick, or equivalentabsorbent material. Oil is poured into the retort by removing its top orscrew neck, the fluid passing down the retort-extension, and through theopenings 01 d d into the reservoir. As soon as the packing is thoroughlysaturated, the cap or screw neck of the retort is restored to position,and the burner screwed on, the sleeve G with its cup being also placedin position. Heat being applied in any suitable manner to the retort tocause the vaporization of its contents suffieiently to start burning,the gas issuing from the burner (as well as that from the openings f fin the stem of the burner) is lighted. The burning jets issuing throughthe openingsffi and striking the cup 9, communicate a considerabledegree of heat to said cup, said heat being conducted by means of thesleeve G directly to the retort D, and from the latter, by means ofitsextension D, right into the middle of the reservoir B.

The heat thus conducted has the effect of vaporizing the liquid contentsof the reservoir, which pass through the openings d d into the extensionD, and thence. into the retort D, where, being subjected to a stillhigher temperature, they become more rarefied, and issue in a gaseousform through the pin-hole 11 into the burner F. To regulate the flow ofgas into the burner through the pin-hole, the screw E is turned so as tocause its point e to enter or be withdrawn from said hole accordingly asit is desired to diminish or to increase the flow.

What I claim as my invention is- 1. In a hydrocarbon-vapor burner, theretort D, formed or provided with an extension, D, in combination withthe reservoir B, said retort and reservoir being relatively arranged,substantially as described, so that the liquid contents of the lattermay come in contact with the walls of the former, so as to secure readyvaporization of the oil, substantially as In testimony that I claim theforegoing I shown and set forth. have hereunto set my hand this 31st dayof 2. In combination with the reservoir B, the August, 1876.
